Specification of Letters Patent.

Patented Aug. 1, 1916.

Application filed November 10, 1915. Serial No. 60,702.

To all whom t may concern: f

Be it known that I, CLrNfroNfB. RIPLEY, la citizen of the United States, `residing at Joplin, in the county of- Jasper and State of Missouri, have invented certain new and useful Improvements in Concentrators, of which the following is a specification. v

My invention relates to ore concentrators and has particular reference lto improvements in that type of concentrators, known as concentrator tables.

As is well known, by those skilled in the art to which this invention,relates arapid uniform reciprocatory longitudinal motion, without lateral or verticalvibrations or jars, in the surface of the table-deck upon which the ore or the like is spread, is the most important factor in producing satisfactoryresults in the, treatment of the ores. Heretofore, as far as I am aware, the priorcon.-

centrating tables, or apparatus of this general character, have Jthe bearings for their table-decks rigidly secured to thebases or foundations, which necessarily subjects theV table-decks to all conflicting, lateral and vertical vibrations, accompanying. such rigid connection. These former constructions also require large, unwieldy and complicated under-deck machinery; and numerous wearing parts, bearings, and upright supports.

An important object of the invention Iis to provide novel and simple yielding means for supporting the table-deck sothat it vis free to reciprocate but will not be subjected to lateral or vertical jars. l

A further object of the invention is to provide .a table-deck, having a maximum -concentrating area or capacity, strength and rigidity, without increasing its weight and cost of manufacture.

A'further object of the invention 1s to 'provide means for tilting the table-deck,

when desired.

A further object of the invention is to provide adjustable means for regulating the tension of .the yielding supportingmeans for the table-deck.

Other objects .and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same, Figure 1 is a side elevation ofk apparatus embodying the invention, Fig. 2 is a plan view of the base, parts removed, Fig. 3 is a transverse sectional view taken on line 3-3 of Fig. l, Fig. 4 is a detail sectional'view through one of the diagonal braces with its attaching element in elevation, Fig. 5 is aplan view of the apparatus, Fig. 6 is an end elevation of the same, Fig-7 is an enlarged end elevation of co-acting bearing elements, Fig. 8 is a' side elevation of the same, parts in section, Fig. 9 is an end elevation of one bearing element, Fig. 10 is an enlarged side elevation of one of the supporting springs, Fig. 11 is a detail section through one of the spring tension adjusting devices, and, Fig. 12 is a bottom plan view of the tabledec t.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 15 designates .a longitudinal horizontal base, embodying 4beams 16, having blocks 17y arranged therebetween and rigidly connected therewith by transverse bolts or rods 18, as more clearly shown in Fig. 10. At one end, the base 15 is provided with an enlarged portion 19 and has an enlarged portion 20 at its opposite end, as shown.

Mounted to, reciprocate above the base 15 is a table-deck 21, embodying, as more clearly shownwin Fig. 12, a frame, comprising pairs of longitudinal beams 22 and 23, havingl notches for receiving pairs of transverse beams 24, rigidly held therein by any suitable` means. Arranged between the inner beams 22 and rigidly secured thereto ,and to thetransverse beams 24 are depend- `mg vertical braces 25, the lower ends of and are attached to the adjacent ends of the beams 24, as the U-bolts 31 are disposed within apertures formed in them.

As more clearly shown in Fig. 3, one of the side rails 32 extends upwardly beyond the top of the table, and serves asa back. Extending transversely of the pairs of beams 24 and rigidly secured within notches formed therein are longitudinal beams 33, upon which are nailed or otherwise secured preferably tongue and groove boards 34, forming the top surface of the table-deck. This top surface is preferably covered with linoleum. As clearly shown in Fig. 5, the opposite edges of the table-deck .are curved longitudinally, whereby the ends thereof are arranged upon the opposite sides of the longitudinal frame, as shown. Secured to the upper surface of the table-deck are longitudinal spaced ribs or strips 35, having the usual function. Rigidly connected with the opposite ends of the table-deck frame, are preferably hollow bearing studs or trunnions 36, bolted or otherwise rigidly connected with end pieces 37, secured to the ends of the beams 22 and 23. This bearing stud may be formed of metal, such as iron or the like. The bearing studs or trunnions 36 are preferably semi-circular in cross-section with their vcurved surface arranged uppermost.

The numeral 38designates a socket bearing member, having an opening 39, semi- `circular in cross-section with its concave side arranged uppermost and its open side lowermost. This socket bearingmember may be yformed of metal, such as copper, and it carries end extensions 40, arranged in longitudinal slots 41, formed in vertical standards 42. The end extensions 40 are bolted or clamped in the openings 41 by bolts 43 or the like. The standards 42 are rigidly attached to the enlarged ends 19 rand 2O of the base 15, as shown at 44. The `socket bearings 40'are provided with grease or oil cups 45, as shown.

The table-deck is moved upwardly, whereby the bearing studs 36 are held up within 'the socket bearing elements 40, by means of compressible coil springs 46, disposed in a Vlongitudinal row, as shown. The lower ends of these coil springs t within annular grooves 47, formed upon caps 48, bolted or votherwise rigidly attached to the blocks 17, 50'

as shown` at 49. Disposed upon the upper end of each coil spring 46 isa cap 50, em-

bodying co-acting adjustable cap members 51 and 52. The cap members 51 and 52 have diagonal or beveled stepped faces 53, for the purpose of adjustment. The lower cap 'member 52 is provided upon its lower end with an annular groove 54, receiving the upper end of the spring 46. Passing through the cap members is a bolt 56, rigidly attached to a block 56', arranged between and rigidly secured to the beams 22, as shown. It is apparent that by rotating the lower cap member 52 clockwise with relation to the upper cap member 51, the tension of the spring 46 may be increased. The table-deckis reciprocated by means of a rod 57, arranged'between the inner means 22 and rigidly attached thereto. Any suitable means may be employed to reciprocate this rod, such as an engine 58, rigidly mounted upon the enlarged end portion 19. Means are provided to tilt the table-deck laterally upon its longitudinal axis, comprising a rod or bar 59, rigidly secured to the bottom of the longitudinal frame comprising the beams 22 and 23. This rod is adapted to bend or yield in a horizontal plane, but is rigid with respect to vertical bending. The outer end of the rod is arranged within a vertical opening or slot 60, formed in a vertical standard 61, and adapted to be clamped in said opening by a bolt 62 or the like. It is thus apparent that the rod or bar 59 does not interfere with the reciprocatory movement of the table-deck.A In operation, the reciproeatory movement ofthe rod 57 is transmitted to the table-deck, which is free to move longitudinally in opposite directions by virtue of its bearing studs 36, slidable in the bearing sockets 40, and held therein, by the springs 59. The material to be treated is fed upon the upper surface of the table-deck in the usual manner, and is subjected to the usual action.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that' various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
